GENERALLY, the topic of fingernail growth is about as interesting as watching paint dry.
As such, it usually goes unnoticed until it is time to reach for the nail clippers.
However, even a dry topic has a fun fact or two – and one is linked to an arguably controversial finger.
Is it true that the nail on the middle finger grows faster than the rest?
VERDICT:
TRUE
Yes, this is indeed true; research indicates the nail on the middle finger tends to grow the fastest, followed by the index and ring fingers.
This is due to a mix of physiological and external factors.
A key factor is finger length, with nails on longer fingers generally growing more quickly.
Usage plays a role too, as nails on the dominant hand tend to grow faster than those on the non-dominant hand.
Another factor is blood flow, as nails grow from a root under the cuticle where new cells are produced and pushed.
Enhanced blood flow delivers more oxygen and nutrients to the nail matrix, promoting faster cell production.
The middle finger, benefiting from its central location, may have slightly elevated blood supply supporting faster growth.
Minor trauma to a nail can also stimulate faster growth by increasing blood and nutrient delivery for repair.
External factors such as diet and overall health influence nail growth rates.
People with nutritional deficiencies often experience slow or uneven nail growth.
Calcium deficiency can cause slow-growing, weak and brittle nails prone to breaking or splitting.
Vitamin D deficiency can also contribute to weak nails because it is crucial for calcium absorption.
People in temperate climates may see slower nail growth in winter due to reduced sun exposure, but that last point is less relevant in Malaysia unless you are indoors all day.
